This tank consists of a long cylinder within which the film makes a U shape. The end of the film is fastened to the top of the tank, a plunger then pushes the film down within the tank. Different versions exist: early models have a rubber bulb to agitate the liquid, the finish is black crackle paint or polished nickel. Made in several sizes up to 3 ½" wide. A Super-Carbine (c. 1934) had a slot to remove the backing paper.

They were extremely popular and produced in several sizes: 127 film size (from 1912), 2 ½", 3 ½", 5" and 7" wide spools. Extra reels could be purchased allowing more than one film to be loaded prior to development. In use the backing paper of the film is attached to a spindle in the wooden box, also in the box is a light-tight celluloid apron, the backing paper, film and apron are wound together on the spindle.
